Christopher Jackson, who played Washington in “Hamilton,” first heard about the show from Lin Manuel Miranda — while they were on stage in a different Broadway show.

Jackson said during MSG Networks Summer Speaker Series that there was a moment in every performance of Miranda’s first hit, “In The Heights,” where they were on stage together, but scenery dropped down in front of them briefly while other actors perform a musical number.

“Lin is one of my best friends so we talk. We aren’t in character, but we are there. We get right to the end of that song and he’s like, ‘Oh by the way, I’ve got my next thing.’”
